Auxiliary brake

Abstract

The invention discloses an auxiliary brake. The auxiliary brake is characterized by mainly being provided with a gearbox, wherein a transmission shaft gear, a gap bridge gearwheel, a gap bridge pinion, a gap bridge axle, a braking gear and a brake axle are arranged in the gearbox; the transmission shaft gear is fixed on a balance transmission shaft of an automobile and is meshed with the gap bridge gearwheel which is connected with the gap bridge pinion through the gap bridge axle, and the gap bridge pinion is meshed with the braking gear; a braking apparatus, a bidirectional hydraulic jack, a supporting spring, an air inlet pipe, a pneumatic tube and the like are arranged outside the gearbox, and the braking apparatus comprises a brake pad fixing seat, a brake pad and a brake drum; the opening end of the brake pad fixing seat is connected with the bidirectional hydraulic jack, and the supporting spring is arranged in the middle of the opening end; the brake drum is fixed on the brake axle. The auxiliary brake has the advantages that the revolving speed of the brake drum is several times lower than that of the balance transmission shaft under the condition that the original configuration of an automobile is unchanged, and the brake pad is completely exposed outside the automobile and is unlikely to be heated; the braking force of an engine is greatly reduced, the running speed is regulated and controlled anytime, the braking frequency is reduced, and the braking time is shortened; the running cost and the running risk caused by water utilization are reduced; particularly, the braking is prevented from being out of control under the condition that a braking system does not work properly.

Description

technical field [0001] The invention relates to a brake, more specifically to a brake for assisting braking of automobiles. Background technique [0002] my country's automobile transportation industry is developing rapidly, and the north-south logistics is becoming increasingly busy. However, the southern and central western regions of my country are mostly mountainous areas with steep and long roads, and downhill roads of more than ten kilometers are not uncommon. As a result, trucks, especially large trucks, must brake continuously when driving downhill. Sparks, even so, sometimes still can't stop, the inner tube can be burned at the slightest, the brakes are out of control, and the car is destroyed. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the prior art and provide an auxiliary brake to alleviate the phenomenon that the temperature of the brake pads of large trucks is too high when the road is steep and ...

However, the southern and central western regions of my country are mostly mountainous areas with steep and long roads, and downhill roads of more than ten kilometers are not uncommon. As a result, trucks, especially large trucks, must brake continuously when driving downhill. Sparks, even so, sometimes still can't stop, at the slightest, the inner tube will be burned, and at the worst, the brakes will lose control, and the car will be destroyed.
