Abstract
The utility model discloses a lock ring type inertia synchronizer, comprising a gear hub (1), a check ring (3) and a sliding gear sleeve (2), wherein a plurality of standard involute splines opened on the inner hole of the gear hub (1) are cooperated with two axles (6) of a speed changer; one end surface of the gear hub (1) is riveted and pressed on the check ring (3) in the trisection way by a rivet and the check ring (3) is riveted and pressed on the end surface of the gear hub (1) by the rivet to form a gear hub assembly together with the gear hub (1); a shifting fork groove (4) is arranged on the excircle of the sliding gear sleeve (2) and oil storage grooves (5) are arranged at the two sides of the bottom diameter of the shifting fork groove (4); a plurality of standard involute splines are arranged in the sliding gear sleeve (2) and two ends of the spline are provided with anti-fallout negative tapers and the spline inversed Y angle position in the two end surfaces of the sliding gear sleeve (2) and in the sleeve are provided with inclined angles. The gear is conveniently shifted along the single direction according to the requirement that the engineering vehicle uses the advance gear and the synchronizing time is shorted and the sliding gear sleeve can be use in a certain range of the use wear along different directions.
Description
Technical field
The utility model relates to a kind of lock ring type inertia synchronizer, is the engineering machinery vehicle Synchromous device of gearbox.
Background technique
The engineering machinery vehicle gearbox adopts the direct gear shift of gear pair usually, and gear shift moment is big, and noise is big.Engineering machinery vehicle part type gearbox also adopts the lock ring type inertia synchronizer gearshift at present, gear is less because engineering machinery vehicle advances generally speaking, particularly forward velocity is slower during load, is the key project that improves the gearbox overall performance so improve at berth-changing strength and on lock in time.
Summary of the invention
The utility model provides a kind of lock ring type inertia synchronizer, it is the unidirectional gear shift that requires of using forward gears according to engineering machinery vehicle, and directed design has also reached that gear shift is light, obviously shorten re-set target lock in time and sliding gear collar can change direction and uses in using the wearing and tearing certain limit.
The utility model has adopted following technological scheme: a kind of lock ring type inertia synchronizer, and it comprises tooth hub, shelves ring and sliding gear collar, described tooth hub endoporus place has some standard involute spliness and matches with two of speed changers; One end face of described tooth hub is by rivet trisection riveting shelves ring, and described baffle ring forms tooth hub assembly by the rivet riveting at tooth hub end face and tooth hub; Described sliding gear collar cylindrical is provided with fork slot, and the both sides, footpath are provided with oil storage tank at the bottom of fork slot; Described sliding gear collar inside is provided with some standard involute spliness, and described spline two ends are provided with anti-off cone, and described sliding gear collar both ends of the surface are provided with the oblique angle to overlapping position, internal spline herringbone angle.
Herringbone angle, described sliding gear collar internal spline two ends angle is 105 °; Described sliding gear collar both ends of the surface are provided with 15 ° of oblique angles of symmetrical inversion to overlapping position, internal spline herringbone angle; Described sliding gear collar internal spline two ends are provided with 6 ° anti-off cone; Described tooth hub, sliding gear collar material are alloyed steel.
The utlity model has following beneficial effect: the utility model is according to three forward gears requirements of gearbox general arrangement, and is at tooth hub one end face riveting baffle ring, spacing during gear shift.Sliding gear collar herringbone angle is improved to 105 ° and be provided with 6 ° of anti-off cones and symmetry, gearshift light and fast during use, and obviously shorten lock in time, and sliding gear collar interchangeable direction in using the wearing and tearing certain limit continues to use more economical material benefit.
