Abstract
The utility model relates to a clutch punching cover of a heavy vehicle, the whole of which is formed by the punching of a steel plate with the thickness of 7mm; diagram spring supporting ring installation positions are processed on 20 concave platforms which are squeezed; two sides of 12 holes which are connected with a flywheel are provided with grooves by punching; the length of the contact part of the flywheel and a spigot which is connected and coordinated with the flywheel is short, thereby being easy to assemble and dissemble; the finishing planes of 12 installation bolt platforms are smaller, thereby being easy to process; and the position for installing a link strip adopts a big opening structure, thereby being easy to ventilate and dissipate heat. The clutch punching cover of the heavy vehicle has the beneficial effects that the stiffness of the clutch punching cover is improved, and the effect of the deformation of the clutch cover to the separate stroke of the clutch and the initial installation position of a separate bearing is reduced.
Description
Technical field
The utility model relates to a kind of clutch stamping cover, especially a kind of heavy-duty car clutch stamping cover.
Background technique
At present, the diaphragm spring clutch that uses on the automobile often adopts the stamping cover structure, compares with tradition casting lid, the advantage that stamping cover has is in light weight, intensity is high, fault in material is little.But clutch stamping cover rigidity commonly used is less, and under the diaphragm spring effect, clutch cover is easy to generate distortion, thereby influences the initial mounting point of clutch release travel and clutch release bearing.
Summary of the invention
The purpose of this utility model is for overcoming above-mentioned the deficiencies in the prior art, provide a kind of rigidity greatly, heavy-duty car yielding, not easy to install clutch stamping cover.
For achieving the above object, the utility model adopts following technical proposals: a kind of heavy-duty car clutch stamping cover, described stamping cover integral body is stamped to form, some concave stations that are provided with diaphragm spring support ring mounting point are arranged on the stamping cover, and the both sides punching press of the some mounting holes that are connected with flywheel on the stamping cover is fluted.
The whole employing of described stamping cover thickness is that the low carbon steel plate of 7mm is stamped to form.
Described groove is smoothly transitted into clutch stamping cover and flywheel contact plane φ 457mm place from the mounting plane φ 445mm of 12 construction bolts of clutch stamping cover.
Finishing planar radial overall dimensions is 23mm on 12 construction bolt platforms on the described stamping cover, and tangential overall dimensions is 26mm.
It is 186mm that driver blade place opening overall dimensions is installed on the described stamping cover.
The cooperation stop portion that is connected with flywheel on the described stamping cover has 3.5mm length to contact with flywheel, and all the other 8mm length are processed into the groove of dark 0.5mm, guarantees clutch assembling dismounting easily.
The beneficial effects of the utility model are, have improved the rigidity of clutch stamping cover, reduce the influence of the distortion of clutch cover to clutch release travel and the initial mounting point of release bearing.

Embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
Among Fig. 1-5, the whole employing of stamping cover thickness is that the low carbon steel plate of 7mm is stamped to form.There are 20 concave stations 1 that are provided with diaphragm spring support ring mounting point at φ 423mm place on the stamping cover, 12 mounting hole 2 both sides that are connected with flywheel at φ 450 places on the stamping cover strike out groove 3, and this groove 3 is smoothly transitted into clutch cover with flywheel contact plane φ 457mm place from the mounting plane φ 445mm of 12 construction bolts of clutch cover.
Finishing planar radial overall dimensions is 23mm on 12 construction bolt platforms on the stamping cover, and tangential overall dimensions is 26mm, easily processing.
It is 186mm that driver blade place opening overall dimensions is installed on the stamping cover, and opening is bigger, and performance of ventilation and heat dispersion is good.
Cooperation stop portion structure by specification accompanying drawing 5 designs that are connected with flywheel on the stamping cover, it has 3.5mm length to contact with flywheel, and all the other 8mm length are processed into the groove of dark 0.5mm, guarantee clutch assembling dismounting easily.
