Special chassis with gate-type transmission system for snow sweeper

Abstract

The invention discloses a special chassis with a gate-type transmission system for a snow sweeper. The special chassis comprises an engine, a transmission, a plurality of transmission shafts, a snow removing mechanism, a transfer case, a front axle and a rear axle. The engine is installed below a cab of a whole vehicle body. The transmission is mounted at an output end of the engine; the transmission shafts comprise a transmission shaft A, a transmission shaft B, a transmission shaft C, a transmission shaft D and a transmission shaft E; the snow removing mechanism is mounted in the middle of the vehicle body; included angles between the transmission shafts B and E and a horizontal plane are reduced compared with that of an existing transmission shaft; abrasion of the transfer case and an axle internal gear is decreased so that a failure rate is greatly reduced, transmission stability is improved, and meanwhile, a noise is reduced; and due to a fact that the included angle between the transmission shaft B and the transmission shaft E is reduced to be smaller than 7 degrees, a height of the main frame and the height of the cab of the vehicle body are decreased, the mass center of thewhole vehicle is reduced, running stability of the vehicle is improved, and meanwhile workers can get on and off the vehicle more conveniently.

Description

technical field [0001] The invention relates to the field of automobile portal transmission systems, in particular to a special chassis for snow removal vehicles with a portal transmission system. Background technique [0002] The power of the car mainly comes from the engine, and the power output depends on the transmission system to the actuator to realize the driving of the car. However, due to the complicated shape, large volume and limited installation position of the exclusive mechanism of the snow removal vehicle, the traditional transmission arrangement cannot solve the problem. The driving power output of the automobile chassis will encounter the problem of structural interference or failure to arrange. [0003] At present, the commonly used method is to increase the installation height of the transfer case and increase the movement angle of the transmission shaft. The included angle is about 17°, so as to obtain a larger installation space. , The improvement of th...

[0002] The power of the car mainly comes from the engine, and the power output depends on the transmission system to the actuator to realize the driving of the car. However, due to the complicated shape, large volume and limited installation position of the exclusive mechanism of the snow removal vehicle, the traditional transmission arrangement cannot solve the problem. The driving power output of the car chassis will encounter structural interference or cannot be arranged

[0003] At present, the commonly used method is to increase the installation height of the transfer case and increase the movement angle of the transmission shaft. The angle is about 17°, so as to obtain a larger installation space. , The improvement of the failure rate of the axle, for this reason, we propose a special chassis for snow removal vehicles with a portal transmission system
