Abstract
The utility model belongs to a clutch and particularly relates to a device used for reducing the towing loss and the wear of a wet-type double clutch. The device comprises an input shaft, a driven disc, a clutch shell, a driving plate, a driven plate, a clutch pressure disc, a return spring and an output shaft. The device is characterized in that release springs are circumferentially distributed at the coupled projecting part of the driving plate and the clutch shell, the release springs are fixed on the driving plate by bolts, and three or more than three release springs are uniformly and circumferentially distributed according to the number of springs on the projecting part on the driving plate as far as possible and arranged at the same side. The device is simple in structure, is safe and reliable, is convenient to process and manufacture, so as to effectively solve the problem that the gap between the driving plate and the driven plate is not uniform in the combination and separation processes and in the separation status of the wet type multi-disc clutch on the premise of increasing smaller cost, thereby reducing the towing loss in the separation status, ensuring the effective separation and the uniform combination in the shifting of the clutch, prolonging the service life, improving the accuracy of shifting control and improving the vehicle shifting comfort and the riding comfort.
Description
Technical field
The utility model belongs to the clutch class, specifically is a kind of device that is used to reduce wet-type dual-clutch band row loss and wearing and tearing.
Background technique
Wet-type dual-clutch generally is made up of friction plate wet clutch more than two, and when cruising, a common clutch is in bonding state, and another clutch is in separated state, and when automobile was in P retaining and N retaining, two clutches were in separated state simultaneously.No matter automobile is in any operating mode, have at least a clutch to be in separated state, because the clutch driving disk and the driven plate relative rotation speed that are in separated state are bigger, if the gap is inhomogeneous between the rotating plate, the too small rotating plate in gap will and between driven plate rub, cause having extra friction torque to produce, transmission efficiency is reduced, and the wearing and tearing of corresponding driven plate also can increase the weight of, therefore, when clutch is in separated state, need to keep the gap between each rotating plate even.
When automobile gear shift, two clutches need carry out combination and lock out operation respectively, when clutch in conjunction with the time, move by shift control mechanism controlled clutch platen, and the gap reduces between the rotating plate, this side rotating plate and driven plate at first begin sliding wear, and along with the platen displacement increases, rotating plate and driven plate begin sliding wear successively, up to complete combination, therefore in the clutch cohesive process, long away from the platen driven plate sliding wear time near the driven plate ratio of platen, so serious wear; In contrast, in clutch disengage process, each driven plate serious wear degree is also inconsistent.Because the combination of clutch is non-linear with sliding wear time of separating and clutch compressing disc displacement during dual-clutch gear-shifting, therefore in a combination-separating cycle, each driven plate degree of wear and inequality, thus indivedual driven plate premature failure caused, influence whole clutch working life.In addition, in clutch combination and separation process, the nonuniformity of driven plate sliding wear and uncertainty have increased the difficulty in the control concerning the double clutch that needs are accurately controlled, directly influence the smoothness and the riding comfort of automobile gear shift process.
Existing wet-type dual-clutch product relies on fully that frictional force realizes the gap is regulated voluntarily between rotating plate and the driven plate, does not have special structure to improve this deficiency.
Summary of the invention
The purpose of this utility model is at the deficiencies in the prior art, and the device that is used to reduce wet-type dual-clutch band row loss and wearing and tearing of a kind of more reasonable structure, more reliable performance is provided.
The utility model is achieved through the following technical solutions:
A kind of device that is used to reduce wet-type dual-clutch band row loss and wearing and tearing of the utility model, comprise input shaft, driven disc, clutch housing, rotating plate, driven plate, clutch compressing disc, return spring, output shaft, it is characterized in that: the projection that cooperates with clutch housing at rotating plate is release spring circumferentially, and release spring is by being bolted on the rotating plate.
The utility model release spring can be selected according to two active distance between commutator segments, it can be helical spring, also can be other elastic elements such as spring sheet, bolt also can adopt alternate manner, as long as can realize the fixation of release spring and rotating plate.
The utility model is simple in structure, safe and reliable, be convenient to manufacturing, under the prerequisite that increases less cost, efficiently solve multi-disc wet clutch MS master-slave moving plate gap problem of non-uniform under combination and separation process and separated state, thereby reduced the clutch row's of being with loss when separated state, effectively separate and evenly combination when guaranteeing clutch gear-shift, problems such as the inhomogeneous indivedual driven plates that cause of driven plate wearing and tearing inefficacy have ahead of time been avoided, prolonged the working life of clutch, be of value to the validity that improves gear shift control, can improve automobile gear shift smoothness and riding comfort better.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
As shown in Figure 1, a kind of device that is used to reduce wet-type dual-clutch band row loss and wearing and tearing, comprise input shaft 1, driven disc 2, clutch housing 3, rotating plate 5, driven plate 6, clutch compressing disc 7, return spring 8, output shaft 9, it is characterized in that: the projection that cooperates with clutch housing 3 at rotating plate 5 is release spring 4 circumferentially, and release spring 4 is by being bolted on the rotating plate 5.
Release spring 4 of the present utility model can be selected according to 5 distances of two rotating plates, it can be helical spring, also can be other elastic elements such as spring sheet, bolt also can adopt alternate manner, as long as realize the fixation of release spring 4 and rotating plate 5.
The utility model release spring 4 should be three or more than, distribute along circumference according to projection quantity on the rotating plate 5 as far as possible evenly, and be installed in the same side.
The elastic parameter of release spring 4 must be passed through accurate Calculation on every group of clutch of the utility model, to guarantee not influence the clutch normal function when clutch combination and separation process and the separated state, and realize self function, the release spring 4 of each clutch should be identical.
The design of the utility model release spring is at the outstanding position of each rotating plate 5 outer rim, with bolt etc. along circumference evenly fix three and more than, elastic device such as helical spring or spring sheet is as separating mechanism, guarantee that distance under any circumstance all equates between the rotating plate, solve the problems referred to above that clutch exists in combination and separation process and during separated state.
