Compressor driving device of bus with air conditioner

Abstract

The invention relates to a compressor driving device of a bus with an air conditioner, which comprises a generator, a compressor, an engine drive wheel, a compressor bracket, a core shaft, a compression spring and a generator, wherein the compressor is arranged on the compressor bracket, a flexible mounting structure adopting a supporting seat of the compressor bracket can wing around the core shaft without a speed-change mechanism and a transition wheel, the engine drive wheel directly drives the compressor, two ends of the core shaft are provided with a vibration reducing rubber device and asupporting seat thereof, wherein the vibration reducing rubber device consists of a transition sleeve and a vibration reducing rubber sleeve; and a vibration reducing rubber piece is arranged betweenthe compression spring and the compressor bracket. The invention simplifies the compressor bracket so as to reduce the weight, improves the drive efficiency, prolongs the service life of working parts of the compressor, lowers the manufacture cost, more importantly prevents the vibration when the compressor of the bus with the air conditioner operates from influencing passengers, and can obviously improve the comfort of the passengers by bus.

Description

Compressor drive for bus air conditioner 【Technical field】 The invention relates to the technical field of automobile manufacturing, in particular to an automobile compressor transmission device for a bus air conditioner on an automobile compressor transmission system. 【Background technique】 At present, most of the automobile air conditioners in my country's buses are non-independent automobile air conditioners. To achieve the best refrigeration effect, the compressor must be controlled within a certain speed range. The speed of the compressor is related to the rated speed of the engine, and is also related to the transmission ratio between the engine and the compressor. In general, it is necessary to set a speed change mechanism between the engine and the compressor, and add a transition wheel to meet the requirements of the required speed of the compressor. Most air-conditioned buses also need to be equipped with a generator, which is driven by the engine through the co...

AI Technical Summary

Problems solved by technology

In most cases, the space position of the engine compartment is only enough to install the compressor, the generator and the speed change mechanism, so that the compression spring that plays a balancing role has to be arranged at the rear of the generator (see accompanying drawing 2), in this case The compressor bracket is easily deformed by force

Since the compressor is fixed on the chassis of the car through the compressor bracket with a rigid structure, the strong vibration generated by the air-conditioning compressor will be transmitted to the passengers, causing some passengers in the rear row to ride uncomfortable; at the same time, the strong vibration generated by the air-conditioning compressor It will also affect the use effect of some parts of automobile air conditioners, resulting in a reduction in their life, especially metal corrugated hoses and compressor clutch bearings

In order to reduce the vibration of the compressor, various compressor vibration reduction mechanisms have appeared on the market, but due to poor results, none of them have been popularized.

At present, the bus air-conditioning vehicles used in developed countries and provided to my country are all equipped with compressor vibration damping mechanisms, and there are many styles, but they are generally one style and can only be used for one type of vehicle. The key is that they are not very suitable for the current situation. Air-conditioned buses in use in my country
