Abstract
The utility model relates to a gear hub of a wet clutch, and solves the problems of the large size and relatively low strength in the existing gear hub of the wet clutch. The gear hub has 28 spline teeth; the large radial diameter of the spline is 121mm; the small radial diameter of the spline is 115mm; the axial sidewall of the hub is evenly provided with two lines of waist-shaped oil holes. The gear hub of the wet clutch is made of excellent hot rolled steel plate with the spinning technology, which greatly improves the strength; the reduction of the spline teeth and the overall size effectively improve the capacity of transmitting the torque and the coefficient of safety of the gear hub, and reduce the weight of the gear hub; the gear hub satisfies the requirements of the automatic transmission for small size, high rotating speed and large torque; and the gear hub has the advantages of excellent technology, easy manufacture and reduced manufacturing cost.
Description
Technical field
The utility model relates to the automatic transmission technical field, relates to a kind of wet clutch tooth hub specifically.
Background technique
Miniaturization Design and weight reduction occupy an important position in modern designs.Automatic transmission size trend is compact, small-sized, and this depends on reducing of each element size; Developing rapidly of engine technology had higher requirement to the torque-transfer capability of various speed changers.
The clutch teeth hub is as one of assembly of automatic transmission mechanical driving part, consider the factor of velocity ratio, the moment of torsion that need transmit is more than 2 times of constant engine output torque normally, and its torque-transfer capability is to the performance of automatic transmission, reliability has significant impact.So for improving safety coefficient, size was bigger when traditional clutch teeth hub designed, tooth hub spline tooth number is more.
The model utility content
Traditional wet clutch teeth hub structure size is big in order to solve, the more problem of the number of teeth, and the utility model provides that a kind of number of teeth is few, intensity is high, the wet clutch tooth hub of compact structure.
Concrete architecture advances scheme is as follows:
A kind of wet clutch tooth hub, comprise hub-like hub body, the outside side of hub axon is a splined shaft, hub body one side is the Bearing Installation face, it is characterized in that: the spline tooth number of described splined shaft is 28, and spline diameter is 121 millimeters of Φ to major diameter, and spline diameter is 115 millimeters of Φ to minor diameter, standard pitch diameter is 118.5mm, and the pitch circle facewidth is 7.719mm;
Described hub axon is uniform two row's waist shape oilholes on sidewall, and long 7 millimeters of oilhole is wide 3.2 millimeters; The length direction of oilhole and hub body axially in the same way;
Every row's waist shaped hole is 14,
Holding attachment face with the hub axon is reference level, and two row's waist shape oilholes axial distance relative and reference level is respectively 15.7 millimeters and 23 millimeters.
Automatic transmission wet clutch tooth hub of the present utility model adopts the hot rolling steel plate of high-quality to process by spinning process, and strength ratio is much higher by the tooth hub that processes such as forging, punching press form.By reducing spline tooth number and reducing overall dimensions, not only tooth hub spline intensity is improved, and the ability and the safety coefficient of tooth hub transmitting torque are effectively improved; Reduced simultaneously the weight of tooth hub greatly.
The utility model can satisfy the requirement of small volume, high rotating speed, high pulling torque automatic transmission; Its good manufacturability is easy to make, and reduces manufacture cost.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further described by embodiment.
Embodiment:
Referring to Fig. 1, a kind of wet clutch tooth hub comprises hub-like hub body 1, and hub body 1 axial outer side surface is a splined shaft, and hub body one side is a Bearing Installation face 2.
The spline tooth number of splined shaft is 28, and spline diameter is 121 millimeters of Φ to major diameter, and spline diameter is 115 millimeters of Φ to minor diameter, and standard pitch diameter is 118.5mm, and the pitch circle facewidth is 7.719mm;
The hub axon is uniform two row's waist shape oilholes 3 on sidewall, and long 7 millimeters of oilhole is wide 3.2 millimeters; The length direction of oilhole and hub body axially in the same way;
The tooth hub in order to make the fine friction plate that flows through of cutting oil energy, has several oil drainage holes by the spline transferring power in the outside on the tooth hub.The tooth hub adopts the steel plate spinning to form, and strength ratio casting, forging, stamping-welded intensity are much higher.
