Description
Technical field
The utility model relates to a kind of automotive transmission parts, particularly automatic transmission case-clutch control mechanism, belongs to the automotive transmission technical field.
Background technique
The automobile that automatic transmission is housed has advantages of that driving is comfortable, can reduce driver's fatigue.Automotives Equipped Automatic Transmissions can be according to the pavement behavior automatic speed-changing and torque-converting, and the driver can watch road traffic attentively absorbedly and can not take sb's mind off sth because of gearshift, and therefore, Automotives Equipped Automatic Transmissions has become a kind of developing direction of Modern Car configuration.Along with the fast development of auto manufacturing technology, the market share of automatic transmission car is improving constantly, and the Consumer is also improving constantly the energy requirement of Automotives Equipped Automatic Transmissions.Automatic mechanical transmission is a type of automatic transmission commonly used, and mechanical transmission can solve the matching problem of power train and engine operating condition preferably, to improve fuel economy and the power character of car load.At present, the clutch control mechanism in the automatic mechanical transmission adopts rack-type mechanism to finish more, makes a return journey to drive with the tooth bar meshed gears by the control motor and rotates, and then carry out displacement on the tooth bar axial direction according to the rotation of gear.This structure, the meshing characteristic based on the gear rack transmission has control accuracy low, has strengthened the control difficulty, and then affects the problems such as the travelling comfort of vehicle integral body and power character.
The model utility content
The utility model is used for solving the defective of above-mentioned prior art and a kind of automatic transmission case-clutch control mechanism that improves control accuracy is provided.
The alleged problem of the utility model solves by the following technical programs:
A kind of automatic transmission case-clutch control mechanism, it comprises motor, motor output shaft is provided with driving gear, specialization is: described mechanism also comprises driven gear, screw rod, nut, described driving gear, driven gear engagement driving, described screw rod, nut power screw connect, and nut maintains static; Described driven gear is sleeved on screw rod one end, circumferentially fixing with screw rod, and the screw rod the other end is provided with the clutch shifter hook.
Above-mentioned automatic transmission case-clutch control mechanism, be symmetrical arranged the groove of perforation in the endoporus of described driven gear, be provided with the ship shape groove with the groove corresponding section on the described screw rod, groove and ship shape groove fasten the cavity that forms two symmetries, be provided with ball in each cavity, ball diameter and cavity height coupling.
Above-mentioned automatic transmission case-clutch control mechanism is provided with three balls in described each cavity, three ball diameter sums are less than the base length of ship shape groove.
The utility model adopts the low problem of gear rack drive control precision to improve for Clutch Control in the existing machinery formula automatic transmission, adopt gear, screw combinations transmission controlling mechanism, wherein gear transmission is delivered to screw rod with rotation, the power screw that form by screw rod, nut realize by the motion conversion of circumference to straight line, utilize power screw under the condition that waits revolution, to reach the purpose of accurate control screw rod displacement distance by setting suitable pitch.But the control accuracy of the utility model Effective Raise automatic gearbox of vehicles clutch, thus shifting comfort and vehicle dynamic quality improved, make it in similar machines formula automatic transmission case vehicle, occupy competitive advantage.
Description of drawings
Fig. 1 is the utility model structural representation.
Attached number in the figure is as follows: 1. motor, 2. driving gear, 3. driven gear, 4. groove, 5. ball, 6. ship shape groove, 7. screw rod, 8. nut, 9. clutch shifter hook.
Embodiment
Referring to Fig. 1, the utility model comprises motor 1, be provided with driving gear 2 at motor output shaft, driving gear and driven gear are connected by meshing transmission, driven gear 3 is sleeved on an end of screw rod 7, screw rod 7 is connected with nut 8 power screw, and nut 8 is fixed block, is provided with the clutch shifter hook 9 that buckles on the Clutch Control shift fork at the other end of screw rod.
Still referring to Fig. 1, be the motion requirement that realizes between screw rod and driven gear can synchronized rotation relatively moving again, in the endoporus of driven gear 3, be symmetrical arranged the groove 4 of perforation, on screw rod 7, be provided with ship shape groove 6 with the groove corresponding section, groove and ship shape groove fasten the cavity that forms two symmetries, be provided with three balls 5 in each cavity, ball diameter and cavity height coupling, three ball diameter sums are less than the base length of ship shape groove 6.
Still referring to Fig. 1, the utility model working procedure is as follows: when the combination that needs solenoidoperated cluthes or separation, input forward or backwards electric current by control system control motor 1, drive driving gear 2 and rotate, driving gear drives driven gear 3 rotations.Driven gear makes the synchronized rotation of screw rod and driven gear by circumferentially fixing between groove 4, ship shape groove 6 and ball 5 formation and the screw rod 7.Because power screw are connected between screw rod 7 and the fixed nut 8, so screw rod also axially moves in rotation, axially movable distance is definite by the revolution of the pitch of screw rod and screw rod.Can calculate according to the pitch of electric current dutycycle, gear ratio and screw rod the displacement amount of screw rod, changing the pitch parameter namely can accurate adjustment screw displacement amount.The displacement meeting of screw rod drives the action of Clutch Control shift fork by clutch shifter hook 9, makes clutch produce certain movement, realizes the purpose of automatic control clutch action.Can drive ball 5 in the 6 interior movements of ship shape groove when the screw axial displacement, when ball moved to the end positions of ship type groove, the ship shape groove can play position-limiting action to ball.
