Abstract
The utility model discloses an automobile generator with vacuum pump, which is characterized in that a screw thread (4) is sleeved on the center hole of a vacuum pump slide block guide frame (1), a screw rod (5) is made on the tail part of a generator shaft (2), and a gap is arranged between the slide block guide frame (1) and the rear plane of a generator rear cover (3). The sliding block guide frame is in threaded combination with the generator shaft, so that combined abrasion drive is realized, the service life of the generator can be prolonged, a fixed gap is reserved between the sliding block guide frame and the rear plane of the rear cover of the generator, the sliding block guide frame and the rear plane of the rear cover of the generator are free of mechanical abrasion, and the performance of a vacuum pump is improved.
Description
The utility model relates to a kind of automobile current generator with vacuum pump, and concrete is the slide block saddle of vacuum pump and combining of generator shaft.
At present, the little Dongfeng Automobile in the automobile of making a leapleap forward, JAC, Zhengzhou that occurs on the market all is to use the generator of band vacuum pump, and vacuum pump is the important component part of above-mentioned brake system of car.Vacuum pump slide block saddle combines with the generator shaft spline, and the on-stream spline flank of tooth will be subjected to the brinelling of 360HZ.Travel about 30,000 kilometers, spline tooth can all grind off, and causes the generator can not the driving sliding block saddle, and vacuum pump is scrapped, and generator is also all scrapped.
The purpose of the utility model is to provide a kind of improved automobile current generator, and it has overcome the above-mentioned deficiency of prior art, prolongs the useful life of generator greatly.
For reaching above-mentioned purpose, the technical scheme that the utility model is taked is: comprise in the utility model: vacuum pump slide block saddle, generator shaft, generator bonnet etc., it is characterized in that: the centre bore of vacuum pump slide block saddle is with screw thread, the afterbody of generator shaft is made screw rod, combines with slide block saddle screw thread.Between slide block saddle and generator bonnet back plane the fixed interval (FI) is arranged.
The utility model is taked above-mentioned structure, has following beneficial effect: because slide block saddle and generator are screwed by screw thread, both have realized that faying face does not have wearing and tearing and drives, can improve the useful life of vacuum pump more than 3 times, be maintained fixed the gap between slide block saddle and generator bonnet back plane, make both not have the machinery wearing and tearing, improved the vacuum pump performance.In addition, the screw thread combination is than spline combination, and it is easier to process, and cost is lower.
Below in conjunction with accompanying drawing the utility model is done and to be described in further detail:
Fig. 1 is the utility model vacuum pump slide block saddle and generator shaft bound fraction structure diagram.
In Fig. 1, the centre bore of vacuum pump slide block saddle 1 is with screw thread 4, and the afterbody of generator shaft 2 is made screw rod 5, and 1 of the back plane of generator bonnet 3 and slide block saddle have the fixed interval (FI).
Claims (2)
1, a kind of automobile current generator that has vacuum pump, comprising: vacuum pump slide block saddle (1), generator shaft (2), generator bonnet (3) etc., it is characterized in that: the centre bore of slide block saddle (1) is with screw thread (4), and the afterbody of generator shaft (2) is made screw rod (5).
2, a kind of automobile current generator with vacuum pump according to claim 1 is characterized in that: between the back plane of slide block saddle (1) and generator bonnet (3) fixed interval (FI) is arranged.
