Problems solved by technology

[0004] In most cases, the space position of the engine compartment is only enough to install the compressor, generator and speed change mechanism, so the compression spring for balance has to be arranged behind the generator (see attached figure 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
[0005] 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

Embodiment Construction

[0034] Below in conjunction with accompanying drawing, provide the specific embodiment of the present invention bus air-conditioning car compressor transmission device.

[0035] See attached Figure 4 . A compressor transmission device for a bus air-conditioning car, including a generator 1, a compressor 2, an engine drive wheel 5, a compressor bracket 6, a core shaft 7, and a compression spring 8, and the generator 1 and compressor 2 are arranged on the compressor bracket 6 Above, adopt the flexible installation structure that the supporting seat of compressor bracket 6 can swing around the mandrel 7, the present invention no longer arranges speed change mechanism 3 and transition wheel 4, and engine drive wheel 5 directly drives compressor 2, for this reason, engine and compression The drive wheel of the machine must match.

[0036] Since the rated speed of the engine matched with the air-conditioned bus in my country ranges from 2000rpm, 2100rpm, 2200rpm, 2300rpm, 2400rpm...

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 a supporting 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 between the 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

【Technical field】 [0001] 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】 [0002] 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 compressor; the speed change ...
