Chapter Two: Steering System 

 

A15 series’ steering system is equipped with standard power steering gear and 

optional mechanical steering gear. 

The power steering gear adopted by A15 series is actually a mechanical gear rack 

steering gear equipped with a power assisted device powered by engine and features 

parts including steering oil pump, steering control valve and power cylinder, etc. 

Working process: engine power drives steering oil pump through 

multi-wedge

, and 

steering oil pump aspirates the power assistant oil in oil tank (ATF oil), and presses 

the oil into steering control valve, then the pressure oil distributed by control valve 

enters into power cylinder to actuate working piston. Since the working piston is 

connected with one end of steering rack, the pressure oil provides function of 

power-assisted steering through the working piston. 

In case the power steering gear fails, the driver shall still be able to complete the 

steering independently. 

Optional mechanical steering gear is a gear rack steering gear, which is powered by 

the driver’s physical energy (hand power), and the power is entirely transmitted by 

mechanical parts.

1. Structure of Steering Post (as shown in the figure) 

2. Assembly Steps of Steering Post: 

1). Assemble bracket ring and steering shaft lock shell spring with an assembling 

press. Apply small amount of lubricant grease around lower bearing and lower inner 

wall of steering post tube, and then press the lower bearing into the steering post tube 

with an assembling press. (Note: be careful not to move upper and lower universal 

joints of steering post tube.)

2). Insert the steering post into post tube from the steering wheel end. 

3). Lock the steering post onto universal joints with bolts. 

4). Fix steering gear lock shell onto steering post tube. Note: Adjust the relative height 

of lock shell and post tube according to the height of preassembled ignition lock 

barrel and combination switch shield. 

5). Fit the serrate adapter sleeve onto steering post, and press it into the position with 

an assembling press by only one stroke to achieve tight fit. 

6). A layer of lithium lubricant grease shall be evenly applied to the contact ring. 

 

II. Disassembly/Assembly of Power Steering Gear and Clearance 

Adjustment 

1. Assembling Power Steering Gear 

1). Assemble steering gear and steering knuckle tie rod assembly onto subframe, and 

tighten the 4 set bolts to specified torque 30Nm. 

 

 

 

 

 

 

2). Connect properly the power steering oil pipe.   

Tightening torque for oil return tube,   

high-pressure oil pipe and steering gear connector   

is 30±3Nm. 

 

3). Tightening torque of the hollow bolt connecting   
high-pressure oil pipe and power steering pump is   
45±3Nm.

2. Checking Power Steering System 

An exhaust is necessary when the hydraulic oil in oil tank looks like emulsified or 

pump noise is too loud (max. 80db under normal condition). Exhaust procedure: jack 

up two front wheels, start engine and turn the steering wheel to both left and right 

extreme positions (do not stay for longer than 2 seconds at extreme positions after 

reached), and repeat turning for several times to gradually exhaust the air in the 

system from oil tank. During the procedure, keep adding hydraulic oil into oil tank 

with the decrease of oil level until a specified level is reached. 

3. Checking Belt Tension 

Worn-out, cracked or blown belt shall be replaced in time. To check belt tension, 

apply moderate pressure with a thumb on a position between the pulleys, and belt 

displacement shall be approximately 10mm. In case the belt is found loose, please 

contact the nearest Chery service station for regulation and maintenance. 

4. Precautions when Checking Power Steering Gear 

Turning steering wheel to extreme positions is prohibited in normal operation, and the 

dwell time is not allowed to exceed 10 seconds in the case of necessity. In case of 

interference check in the minimum turning radius test on assembly PG, the dwell time 

of steering wheel at extreme positions is also not allowed to exceed 10 seconds. When 

a loud noise from power steering oil pump is heard during steering, turn back the 

steering wheel a little until the noise is gone. Unoiled working of power steering 

pump is strictly prohibited. If steering is felt heavy in operatoin, stop the vehicle 

immediately to check and repair. 

 

III. Inspection Items of Power Steering System 

Bent steering post, worn or damaged safety coupling, inelastic spring shall be repaired 

or replaced. 

1. Routine Inspection 

(1). Check if the set bolts are loose. 

(2). Check if the steering wheel free play is appropriate, and adjust or replace steering
