Description

Simple retarder for automobile

Technical Field

The utility model relates to an automobile retarder specifically is a simple and easy retarder of car.

Background

The automobile usually adopts the traditional drum brake to brake and the electric turbine retarder or the scheme matched with the hydraulic retarder. When the drum brake is matched with the electric turbine retarder, the electric turbine retarder has much larger power consumption than the original electric control system on the automobile, so that the load of the storage battery is increased. When the automobile runs under the non-retarded speed state, the transmission shaft drives the rotor, and 1% of power of the engine is consumed. Due to the limitation of the radial dimension, the electric turbo retarder cannot obtain a sufficiently large braking torque, and the braking torque is reduced as the vehicle speed is reduced. The rotor temperature may rise to 650 deg.c due to poor heat dissipation conditions, and thus cannot be used for a long time. Hazardous chemical substance vehicles should be used with caution. The electric turbine retarder is high in cost due to the fact that copper materials are consumed. When the drum-type controller is matched with the hydraulic retarder, the braking torque of the hydraulic retarder also changes along with the rotating speed, and when the speed of the vehicle is lower than 30 km/h, the retarder loses the retarding effect. The hydrodynamic retarder has long reaction time, so the hydrodynamic retarder can not be matched with an automobile ABS for use. When the hydraulic retarder is lack of oil, the hydraulic retarder can not generate braking torque, but consumes about 4% of engine power. In addition, the electric turbine retarder and the hydraulic retarder are sleeved on the transmission shaft, and the transmission shaft must be disconnected during assembly and disassembly, so that inconvenience is brought to maintenance. The two retarders have to have parts which have certain technical requirements and rotate along with the transmission shaft, so that the service life of the retarder is limited. Because the braking capability of the electric turbine retarder and the hydraulic retarder is insufficient, the electric turbine retarder and the hydraulic retarder cannot be used on a heavy-duty automobile. On heavy-duty vehicles, the problem of brake drum overheating is usually solved by spraying cold water to reduce the temperature. This makes the vehicle uneconomical to be equipped with a heavy water tank for operation. And the brake drum is easy to be damaged in the process of repeatedly heating and cooling, so that the safety of the automobile is influenced.

Disclosure of Invention

The utility model aims to provide a simple retarder for an automobile, which can be used on a heavy automobile to replace a method for spraying a brake drum by cold water.

The design scheme of the utility model is as follows: a simple retarder for an automobile comprises a telescopic cylinder, a cylinder support, a piston rod, a lever support, a lever and a friction block, wherein the cylinder support is fixed on a crossbeam of the automobile through a bolt; the upper end of the lever is hinged with the piston rod through a pin, the lower end of the lever is hinged with a lever bracket through a pin, and the lever bracket is fixed on an automobile beam through a bolt; the friction block is fixed at the bottom of the lever.

The retarder is symmetrically arranged on the left and right of the automobile beam, so that the friction block is aligned to the wheel.

The cylinder support and the lever support are arranged on the automobile beam according to the front and rear positions.

When the piston rod in the telescopic cylinder extends out, the lever is pushed to rotate around the pin, the bottom friction block is in contact with the ground, friction force between the bottom friction block and the ground is obtained, and the vehicle can be slowed down.

A simple retarder for an automobile can obtain enough braking force and generate a good braking effect. It is no longer installed on the transmission shaft, and is convenient to install, dismantle and maintain. It has no rotating parts, reliable use, long service life and no consumption of engine power. Its braking torque is not affected by the speed of automobile and the working state of ABS. The automobile radiator can directly discharge the heat generated by the automobile radiator to the air without influencing any part of the automobile without a heat dissipation device. The cost of the electric turbine retarder is about 20 percent of that of the electric turbine retarder with the same effect.

The telescopic cylinder 3 can adopt a common telescopic hydraulic cylinder, and can obtain a very long working stroke when extending out to push the lever to do work.

A simple retarder for an automobile can obtain different downward pressures on a friction block 7 by only adjusting the size between an upper pin 9 and a lower pin 10 on a lever 8 so as to adapt to the requirements of different vehicles. When the telescopic cylinder 4 extends in operation, the piston rod 4 extends out, the push lever 6 rotates around the lower pin 10, the distance between the bottom friction block 7 and the ground is reduced until the bottom friction block 7 contacts with the ground, friction force between the bottom friction block 7 and the ground is obtained, and the vehicle can be slowed down.
