Abstract
The utility model relates to a dead-point-free variable gear drive rear axle controlling first gear thrust friction. A clutch control sleeve is inserted into a second gear to form a control clutch, a friction plate is fixedly connected with the clutch control sleeve, a differential gear is connected with a middle shaft of a first-gear one-way part and a middle shaft of a reverse gear one-way part in a meshed mode, and a second gear, a first gear, a reverse gear and a power input shaft form mesh connection. When a motor rotates forward, a clutch in the second gear obtains a second gear; when an electromagnetic thrust valve works, a push rod is pushed to the clutch control sleeve under the action of a steel ball, the friction plate is pressed on the first gear and friction force is formed; the first gear rotates, the clutch control sleeve fixed to the friction plate is driven by the friction force to move, the clutch in the second gear is disengaged due to moving of the clutch control sleeve, and accordingly the first gear one-way part works to form a first gear with the first gear; power is output through the differential gear, when the motor rotates reversely, the reverse gear one-way part works to output the power from the differential gear to form a reverse gear, and the service life of the friction plate is prolonged.
Description
Technical field
The utility model is that a gear tooth thrust friction control drives back axle without dead point variable block, belongs to field of mechanical technique.
Background technique
The design in past and patent application are that friction plate is designed on the friction ring of same gear, design just goes wrong like this, all the time solenoid valve will be in pulling forcing state, namely to be electrified always and keep pulling force to make friction plate produce the retentive control of friction ability, to waste so many electric power, do not reduce the friction plate life-span, new scheme is the mode that friction plate is acted on another gear and change thrust control into.
Model utility content
The purpose of this utility model is to provide a gear tooth thrust friction control and drives back axle without dead point variable block, has realized in the time of the most frequently used two gear electromagnetic push valve no electric circuit and friction plate and and keep off tooth and do not form the working effect of friction, has improved the object in friction plate life-span.
Its objective is such realization, a gear tooth thrust friction control drives back axle to be made up of electromagnetic push valve, push rod, steel ball, two gear teeth, clutch for clutch control cover, friction plate, a gear tooth, the tooth that reverses gear, differential tooth, gear one-way element, a power input shaft, the one-way element that reverses gear without dead point variable block; Electromagnetic push valve is connected with push rod, between clutch for clutch control cover and push rod, steel ball is housed, and clutch for clutch control cover inserts formation control clutch in two gear teeth, and push rod and steel ball are to install through two gear teeth.Friction plate is fixedly connected with clutch for clutch control cover, and friction plate and a gear tooth are close to install and form rubbing surface, one gear one-way element is arranged in a gear tooth, the one-way element that reverses gear is contained in and reverses gear in tooth, differential tooth and meshing a connection of axis of keeping off one-way element, the one-way element that reverses gear, wherein, two gear teeth, a gear tooth, the tooth that reverses gear form meshing connection with power input shaft.
When motor forward, the two clutch work that keep off in tooth obtain two gears, in the time that electromagnetic push valve is worked, promoting push rod acts on clutch for clutch control cover and friction plate is pressed on a gear tooth through steel ball, form frictional force, the rotation of one gear tooth drives the clutch for clutch control cover fixing with friction plate mobile through frictional force, the movement of clutch for clutch control cover makes the throw-out-of clutch in two gear teeth, so a gear one-way element job and a gear tooth form a gear, by differential tooth outputting power, when after motor reversal, clutch in two gear teeth and a gear one-way element are not worked, the one-way element work of reversing gear forms power to reverse gear from the output of differential tooth, realize the working effect that in the time of the most frequently used two gear electromagnetic push valve no electric circuit and friction plate and keep off tooth and do not form friction.Improve the friction plate life-span.
Accompanying drawing explanation
Concrete structure of the present utility model is provided by following examples and accompanying drawing:
Fig. 1, be that the utility model one keeps off the control of tooth thrust friction and drives rear axle structure schematic diagram without dead point variable block.
In Fig. 1,1, electromagnetic push valve, 2, push rod, 3, steel ball, 4, two gear teeth, 5, clutch for clutch control cover, 6, friction plate, 7, a gear tooth, 8, the tooth that reverses gear, 9, differential tooth, 10, a gear one-way element, 11, power input shaft, 12, one-way element reverses gear.
Embodiment
Describe the specific works situation the utility model proposes in detail below in conjunction with Fig. 1, in Fig. 1
When motor forward, the two clutch work that keep off in tooth 4 obtain two gears, in the time that electromagnetic push valve 1 is worked, promoting push rod 2 acts on clutch for clutch control cover 5 and friction plate 6 is pressed on a gear tooth 7 through steel ball 3, form frictional force, the rotation of one gear tooth 7 drives the clutch for clutch control cover 5 fixing with friction plate 6 to move through frictional force, the movement of clutch for clutch control cover 5 makes the throw-out-of clutch in two gear teeth 4, so gear one-way element 10 job form a gear with a gear tooth 7, by differential tooth 9 outputting powers, when after motor reversal, clutch in two gear teeth 4 and a gear one-way element 10 are not worked, the one-way element 12 that reverses gear is worked power to export to form from differential tooth 9 and is reversed gear, realize the working effect that in the time of the most frequently used two gear electromagnetic push valve 1 no electric circuit and friction plate 6 and keep off tooth 7 and do not form friction.
