Abstract
The utility model relates to a novel double-clutch type automatic gearbox side cover assembly which consists of a fixed sleeve, a seal ring and a side cover, and is characterized in that short and thin ribs are arranged on the outer surface of the side cover, the ribs are distributed more densely and in a reticular structure; and the seal ring is fixedly connected to the peripheral edge of the side cover. The fixed sleeve is fixedly connected to the periphery of the side cover and is positioned outside the seal ring. The novel double-clutch type automatic gearbox side cover assembly has the characteristics of light weight, high strength, strong impact resistance, few fastening bolts, convenience in assembly and the like.
Description
Technical field
The utility model relates to a kind of novel double-clutch automatic transmission side cover assembly, belongs to the automatic gearbox technical field of auto manufacturing.
Background technique
Along with the fast development of automobile pollution and the rapid increase of amateur driver's quantity, automatic gearbox is just presenting fast development trend.Present automatic gearbox mainly contains hydraulic mechanical type automatic transmission (AT), stepless speed variator (CVT) and double-clutch automatic transmission (DCT).
Realizing on automobile that the self-shifting speed changer is the hydraulic mechanical type automatic transmission, be called for short AT, also is present most widely used automatic gearbox.It does not cut off power shfit, has starting, gear shift is smooth-going, but resisting moment is changed advantage such as self adaption.But shortcomings such as it also has complex structure simultaneously, and difficulty is made, and transmission efficiency is low.
Manually fixedly the shaft type gear-shift transmission is the step change driving mechanism, and its advantage is that efficient is high, and cost is low, and mature production technology is widely used in China at present.Shortcoming is a gear shift difficulty, and power interruption during gear shift requires pilot control skilled, so people expect that it can realize automation.Computer Control Technology makes this gear realize that automaitc shfit becomes possibility.Double-clutch automatic transmission (DCT) is the automatic mechanical transmission of a new generation; It has inherited high, the many advantages such as installing space is compact, in light weight, low price of manual transmission transmission efficiency; Fundamentally solved the cut-out power shfit problem that electric control mechanical type automatic speed variator exists; Greatly improved the gear shift travelling comfort, guaranteed that vehicle has good power character and shift characteristic.
In double-clutch automatic transmission, each gear driving gear of speed changer by strange, even number gear respectively with input shaft on two clutch C1, C2 being provided be connected, clutch C1, C2 replace transferring power to realize gear switch.
During DCT work, with certain gear operation, electrical control unit of automatic transmission (TCU) is judged next gear that is about to the work of getting into according to the signal of related sensor to vehicle earlier; Because of this gear clutch separation transferring power not also,, mesh this gear in advance so instruction hydraulic control solenoid valve is controlled gear-shifting actuating mechanism very easily; When vehicle operating reaches shift point; The clutch separation that only need will work simultaneously with another clutch, then makes automobile go with next gear.In gearshift procedure, the power of motor constantly is passed to wheel all the time, so the gearshift procedure of accomplishing like this is a power shfit.Vehicle implementation timing, will improve the gear shift travelling comfort greatly, simultaneously guarantee that also vehicle has good and economic, aspects such as vehicle oil consumption and discharging are made moderate progress.
Summary of the invention
The purpose of the utility model provides a kind of novel double-clutch automatic transmission side cover assembly, and it has light weight, and intensity is high, strong shock resistance, characteristics such as clamping bolt quantity is few, and is easy to assembly.
The technological scheme of the utility model is achieved in that a kind of novel double-clutch automatic transmission side cover assembly; Form by fixed cover, seal ring, side cover; It is characterized in that: the side cover appearance has designed short and thin muscle; Distribute closeer and have reticular structure, seal ring is fixedly connected on edge, side cover surrounding, and fixed cover is positioned at outside the seal ring around being fixedly connected on side cover.
The utility model good effect is to have light weight, and intensity is high, strong shock resistance, characteristics such as clamping bolt quantity is few, and is easy to assembly.
Description of drawings
Fig. 1 is the structural drawing of the utility model.
Fig. 2 is the sectional drawing of the utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is done further description: like Fig. 1, shown in 2, a kind of novel double-clutch automatic transmission side cover assembly is made up of fixed cover 1, seal ring 2, side cover 3; It is characterized in that: side cover 3 appearances have designed short and thin muscle 4, adopt plastic materials to process, and distribute closeer and have a reticular structure; Intensity is high; Can effectively prevent the bump of side, little apart from speed changer inner valve body distance, compact structure; Seal ring 2 is fixedly connected on edge, side cover 3 surrounding; Fixed cover 1 is positioned at outside the seal ring 2 around being fixedly connected on side cover 3, and seal ring and side cover are integrated, and fixed cover reduces fixing bolt and acts on the preload pressure that plastic side covers.
