Abstract
The utility model discloses a kind of Novel brake master cylinder adopting mechanical transmission-type, push away below cover and brake cylinder casing joint in braking and be provided with back-up ring and brake piston apron, described back piston is located at the gap location of brake pushrod and brake cylinder casing, described brake cylinder casing is also provided with return spring, this return spring is that Split type structure is made up of front return spring and rear return spring, and described front return spring is connected by secondary piston with rear return spring.The utility model compact structure, ensure that the mechanically operated life-span, and the sealing of brake cylinder casing and brake pushrod is strong, before and after soluble change piston motion state thus play fuel-efficient object, and then improve the braking of clutch.
Description
Technical field
The utility model relates to automobile brake clutch field, particularly relates to a kind of Novel brake master cylinder adopting mechanical transmission-type.
Background technique
Automobile is divided into automatic catch and manual gear as you know, and the clutch of automatic catch, is also referred to as automatic clutch control system, is a kind of Intelligent clutch control system researched and developed for manual vehicle.On the basis not changing former car gearbox and clutch, by installing a set of autonomous system additional, by micro computer control clutch from and conjunction, thus reach the effect of " drive need not step on clutch ".
And although automatic catch is relatively good as you know opens but oil consumption is large, the reason of pursuit is that hydraulic type automatic clutch can comparatively oil consumption, so only have the power reduced required for mechanical transmission to reduce oil consumption.
Model utility content
For the problems referred to above, the utility model provides a kind of Novel brake master cylinder adopting mechanical transmission-type.
For solving the problems of the technologies described above, the technological scheme that the utility model adopts is: a kind of Novel brake master cylinder adopting mechanical transmission-type, comprise: brake pushrod, brake pushrod left end pins a push rod latch by hexagon nut, braking system is arranged with in the middle part of described brake pushrod, it is characterized in that: described braking system comprises braking and pushes away cover, brake cylinder casing, oil-feed bolt, secondary piston, back piston, oil-feed packing ring, it is wavy shaped configuration that described braking pushes away cover, this braking is pushed away cover and is flexibly connected by male-female engagement and brake cylinder casing, push away below cover and brake cylinder casing joint in braking and be provided with back-up ring and brake piston apron, described back piston is located at the gap location of brake pushrod and brake cylinder casing, described brake cylinder casing is also provided with return spring, this return spring is that Split type structure is made up of front return spring and rear return spring, described front return spring is connected by secondary piston with rear return spring,
Further, the cross-section area of described brake pushrod is 2 times of push rod latch;
Further, described back piston is provided with buckle, and this buckle is engaged each other by brake piston apron and brake cylinder casing;
Further, described male-female engagement is provided with clip for pushing away on cover in braking, and this clip is stuck in the clearance groove on brake cylinder casing, and the male-female engagement of described clip and clearance groove adopts Spielpassung;
From the above-mentioned description to the utility model structure, compared to the prior art, the utility model tool has the following advantages:
A kind of Novel brake master cylinder adopting mechanical transmission-type of the utility model, the oil consumption of existing automatic catch clutch 40% can be reduced, and its compact structure, ensure that the mechanically operated life-span, the sealing of brake cylinder casing and brake pushrod is strong, before and after soluble change piston motion state thus play fuel-efficient object, and then improve the braking of clutch.
