Steering gear box assembly
The steering gear box assembly consists of power cylinder and control valve. The power cylinder has a
cylinder, piston and piston rod. The control valve directs the oil to one end face of the piston to enhance
the steering force. There is a safety check valve which lets the driver steer manually when there is a
malfunction in the hydraulic circuit.
8. STEERING SYSTEM LAYOUT
1) HPS (Hydraulic Power Steering)
The hydraulic pump is a vane
type pump and consists of the
flow control valve and pressure
relief valve.The oil reservoir sends the oil to
the power steering pump and
receives the oil from the power
steering gear.There is a shock absorber which
is folded in the axial direction
when the vehicle is crashed and
a ignition switch assembly on
the column shaft.
The lower shaft minimizes the
torque change using a CV joint
which has constant angular
speed.

1. OVERVIEW
The propeller shaft is a thin steel pipe which transfers the power from the transmission to the E-coupling,
and has high resistance to torsion and bending.
The propeller shaft has the universal joint (cross axle) mounted on the center of the shaft and splines for
the slip joint on the E-coupling side to accommodate the height and length changes which occur as the
shaft rotates at high speed.
And the rubber bushing for center bearing in the center of the propeller shaft keeps the balance of the
shaft and absorbs its vibration.
Function of propeller shaft
Transmits driving torque.
Accommodates the angle change (universal joint / CV joint).
Accommodates the axial length change (splines for the slip joint). -

1. OVERVIEW
The suspension is the device to connect the axle and vehicle. It absorbs the vibrations and impacts from
road surface, which enhances the comforts, driving force, braking force and drivability.

1) Front Suspension (Macperson Strut Type)
Front suspension supports the vehicle weight and absorber the vibration from tires. And, in this type of
suspension, the steering linkage tie rod is mounted on the knuckle.
Macperson strut type suspension is the independent suspension which has the spring on the strut
integrated with shock absorber. The lower arm is installed on sub frame and large strut damper is
installed on the knuckle to support the tire. This type of suspension is normally applied to the vehicle with
monocoque body, especially on the front wheel drive type. The upper part with spring is mounted at
body mount and the strut with shock absorber is linked on the steering knuckle.
Advantages
Compact and simple design
Stable wheel alignment
Good load distribution and easy installation
Less effect from tire up/down movement 1.

Disadvantages
Comparatively weak to the impact from road surface and lateral shock due to long strut and single
swing arm 1.

1) Components
(1) PTU (Power Transfer Unit)
and transfer it to E-coupling to distribute the torque to rear wheels.
(2) E-Coupling (Electronic Coupling)
E-Coupling transfer the engine torque from PTU to rear axle and controls to distribute it between front
wheels and rear wheels.
(3) E-Coupling Control Unit (ECU)
E-Coupling controls the current (clutch engagement force) of EMCD in E-Coupling according to CAN
signals (wheel speed, engine torque, pedal position, ABS/ESP signals).
