The __________ splits engine power between the front and rear axles of four-wheel drive vehicles.
transmission linkage |
|
transfer case |
|
universal joint |
|
master cylinder |
The transfer case splits engine power between the front and rear axles of four-wheel drive vehicles.
A vehicle's lighting system is protected from current spikes by:
the battery |
|
fuses and circuit breakers |
|
the alternator |
|
the voltage regulator |
The lighting system consists of interior lights, instrument panel lighting, headlights, and taillights. Like household electrical circuits, the vehicle's lighting system is protected from current spikes by fuses and circuit breakers.
Coolant is circulated through the engine by the:
water jacket |
|
radiator |
|
camshaft |
|
water pump |
The water pump is driven by a belt connected to the crankshaft and ensures that coolant moves through the engine and radiator.
Control arms connect a vehicle's suspension to the frame. The connection to the wheels is through:
ball joints |
|
bushings |
|
pins |
|
knuckles |
Control arms (upper and lower) connect a vehicle's suspension to the frame. The connection to the wheels is through ball joints which allow the control arms to turn and move up and down simultaneously. The frame connection uses bushings.
Which of the following transfers the torque from the transmission to the drive wheels at a constant speed while accomodating the up and down movement of the suspension?
control arms |
|
constant velocity (CV) joint |
|
springs |
|
transfer case |
Constant velocity (CV) joints are located at both ends of a half shaft and their purpose is to transfer the torque from the transmission to the drive wheels at a constant speed while accomodating the up and down movement of the suspension. The inner CV joint connects the shaft to the transmission and the outer CV joint connects the shaft to the wheel.
