Abstract
The utility model discloses a kind of automobile gearbox rear end caps, include cover, mounting hole is provided in the cover, the bottom surface of the cover is step type, and match with the bottom surface of the cover and speed change box back, it is characterized in that the bottom surface of the cover has the oil groove for machine oil circulation, the oil groove is radially arranged in the bottom surface of cover, baffle is installed above the oil groove, the both ends of the baffle have the oil inlet and oil outlet communicated with oil groove, the through-hole communicated with oil groove is offered on the baffle, and the through-hole passes through connecting tube and the center axis connection of gearbox.The utility model increases machine oil circulation, ensures gear sufficient lubrication, reduces noise, and rapid cooling prolongs the service life.
Description
Technical field
The utility model relates to a kind of improvement inventions of automobile gearbox rear end cap.
Background technology
Gearbox is the important component of automobile engine, and gearbox includes housing and rear end cap, rear end cap and shell
Body is tightly connected, and gearbox is made to be in sealing state, to be full of machine oil in gearbox, machine oil has lubrication, Noise Reduction.Tradition
Gearbox rear end cap only plays sealing function, avoids oil leak, but the machine oil in gearbox needs the tooth made in gearbox that circulates
Wheel is fully contacted with machine oil, so as to play Noise Reduction, and prolongs the service life of gearbox.
Invention content
In view of background technology, the technical problem to be solved by the present invention is to provide a kind of improve to become
The automobile gearbox rear end cap of the velocity of liquid assets of fast inner box-machine oil.
In order to solve the above-mentioned technical problem, the utility model adopts the following technical scheme that realize：This kind of automobile becomes
Fast box back lid includes cover, is provided with mounting hole in the cover, and the bottom surface of the cover is step type, and with it is described
The bottom surface of cover matches with speed change box back, it is characterised in that the bottom surface of the cover has the oil groove for machine oil circulation, institute
The bottom surface that oil groove is radially arranged in cover is stated, baffle is installed above the oil groove, the both ends of the baffle have and oil groove
The oil inlet and oil outlet communicated, offers the through-hole communicated with oil groove on the baffle, and the through-hole by connecting tube with
The center axis connection of gearbox.
The bottom surface of the cover has several oil circuits communicated with oil groove.
The baffle is connect with cover for electric resistance welding.
The rear end cap of the utility model increases oil groove, and oil groove is connected with central shaft in gearbox, the volume machine in gearbox
Oil enters oil groove by the oil inlet on rear end cap, and part machine oil is discharged from oil outlet, and part machine oil enters speed change from connecting tube
It in the central shaft of case, is come into full contact with by central shaft and the gear in gearbox, machine oil enters oil groove by oil inlet again, so follows
Ring increases velocity of liquid assets of the machine oil again in gearbox, the gear in gearbox is made fully to be merged in the process of running with machine oil, is carried
High lubricity reduces the noise of engaged gears generation and absorbs the heat that gear friction generates, and extend gearbox uses the longevity
Life.
Description of the drawings
Fig. 1 is the structure diagram of the utility model.
Fig. 2 is the sectional view of the utility model.
Specific embodiment
The operation principle of the utility model and its related details are further described below in conjunction with the accompanying drawings.With reference to attached drawing, this kind
Automobile gearbox rear end cap includes cover 1, mounting hole 6 is provided in the cover 1, the bottom surface 2 of the cover is ladder
Type, and match with the bottom surface of the cover and speed change box back, the bottom surface 2 of the cover has the oil groove 5 for machine oil circulation,
The oil groove 5 is radially arranged in the bottom surface of cover, and the bottom surface of the cover has several oil circuits 7 communicated with oil groove, oil circuit 7
Setting increase the circulation of machine oil, the top of the oil groove 5 is equipped with baffle 3, and the baffle 3 is electric resistance welding with cover 1
Connection, electric resistance welding connection are more secured；The both ends of the baffle 3 have the oil inlet 8 communicated with oil groove and oil outlet 9, described
The through-hole communicated with oil groove is offered on baffle, and the through-hole passes through connecting tube 4 and the center axis connection of gearbox.
The cover is mounted on by screw on gear box casing, and passing through oil sealing makes gearbox be in sealing state, keeps away
Exempt from the machine oil exudation in gearbox.When gearbox is run, gear rotates, and the machine oil in gearbox is by oil inlet or through cover bottom
The oil circuit in face enters oil groove, and the part machine oil in oil groove is discharged from oil outlet, and part machine oil then enters gearbox by connecting tube
Central shaft in, flow through each gear, machine oil enters oil groove by oil inlet again, so recycles, the utility model increases machine oil
Circulation, gear is made to be come into full contact with machine oil, ensure gear sufficient lubrication, and machine oil by gear friction generate heat inhale
It receives, machine oil circulation is radiated, and high temperature is avoided to influence speed change casing working, is prolonged the service life, meanwhile, lubrication can fully reduce
The noise that gear generates.
