The NV4500 was a very popular manual gearbox and was installed on many lightweight Toyota, Ford, Jeep, General Motors and Dodge trucks. The New Venture Gear 4500 – commonly known as the NV4500 – is a New Venture Gear 5-speed manual transmission that was installed on General Motors and Chrysler machines from 1991 to 2007. Vehicles with different types of drive have significant differences in the design, both in terms of composition and construction. The front and rear wheels are driven by four-wheel drive cars. If the rear wheels are used as drive wheels, the vehicle has rear drive and if the front wheels are used as drive wheels, the vehicle has front drive. In the transmission design, front, rear and front wheels can be used as driving wheels. Each of these types of power units has its pros and cons. Also, today you can choose from several types of automatic transmissions: hydro-mechanical gearbox (conventional “automatic”), manual transmission with two clutches, robotic gearbox and CVT. In this way, human involvement is minimized. However, such a gearbox is more convenient to use, especially when driving in the city, because it does not require constant switching on/off the clutch. If a manual gearbox has a simple design, the automatic transmission has more units and assemblies, which in turn affects the cost of its manufacture, repair and operation. The standard set of transmission consists of several components: clutches, gearboxes, cardan gear, main gear, differential gears, axle halves.ĭepending on the layout (front, rear, all-wheel drive) transmission can include other units: CV joints (joints of equal angular speeds), transfer gearboxes, friction, viscous clutches. To reduce friction and cool the unit special motor oils are used, which must be regularly changed according to the instructions of the car manufacturer. Its parts, assemblies and mechanisms are made of wear-resistant materials capable of withstanding high mechanical loads, exposure to temperature fluctuations, chemical agents. Based on the type of transmission it can be divided into mechanical, electrical, hydro-volume and combined. The main purpose of this unit is the distribution of torque from the motor flywheel to the drive wheels. This is a multi-knot mechanism and is called a transmission. To solve the problem you can install an intermediate power unit that will reduce the motor force to the required rpm and transfer it to the drive wheels. This will interfere with the weight of the car and the friction force arising from the coupling of the wheels with the road surface. Why? The motor of the car will not have enough capacity in a fraction of a second to spin the wheels to the motor operating speed. If you install the internal combustion motorunder the hood and try to connect the clutch to the crankshaft, the motor will simply stall.
