Abstract
The invention relates to a rear matching vehicle running gear, which comprises an axle and wheels, and also comprises chute structures symmetrically arranged at two sides of the axle, wherein each chute structure comprises a support base, a chute and a damping rubber pad, the lower parts of the support bases are fixed with the axle, the upper parts of the support bases are inserted into the interiors of the chutes, after being matched, the support bases and the chutes are connected by bolts, the damping rubber pads are arranged between the top surfaces of the upper parts of the support bases and the bottoms of the chutes, and the axle and the wheels are connected by bearings. According to the rear matching vehicle running gear, a single axle box is omitted, so that the wheels rotate independently and are suspended inside; the tops of the chutes is welded in a bottom frame, so as to play roles of bearing the whole vehicle, transmitting traction, and allowing a locomotive to turn; the damping rubber pads are used for damping the whole vehicle, so as to guarantee the vehicle to run stably; the rear matching vehicle running gear has a simple structure, simplifies the manufacture process, shortens the production cycle, and is low in cost and good in universality, and the running gears of various rear matching vehicles (such as a mortar vehicle and a segment vehicle) are exchangeable.
Description
Technical field
The present invention relates to the traveling portion of conveyance vehicle after industrial and mineral.
Background technology
At present, in industrial car system, there is the rear conveyance vehicle of different size, as mortar vehicle, segment car etc., the traveling portion of these vehicles adopts the form of the additional damping spring of structure of axle box of running mechanism of train portion conventionally, as shown in Figure 1, mainly formed by damping spring 10, journal box body structure 11, bearing 7, wheel 2 and axletree 1, the Undercarriage structure of conveyance vehicle after damping spring 10 upper ends connect, lower end adapter shaft body structure 11, journal box body structure 11 is for transmitting tractive power and meet turning function, and axletree 1 is connected by bearing 7 with journal box body structure 11.The shortcoming of this form is
:(1) complex structure, accessory precision is high, and technique ensures that difficulty is large, and the production cycle is long.(2) fault rate is high, and dismounting difficulty is large, and past-sale service is very inconvenient.(3) processing accessory is many, and parts precision, requirement of strength are high, and cost is too high; (4) each vehicle accessory disunity, of a great variety, and buying mostly is hand-to-mouth buying, is unfavorable for batch manufacturing tissue.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of simple in structure rear conveyance vehicle traveling portion.
For solving above technical matters, the present invention improves existing rear conveyance vehicle traveling portion, conveyance vehicle traveling portion after one of the present invention, comprise axletree and wheel, also comprise the sliding groove structure that is symmetricly set in axletree both sides, sliding groove structure comprises supporting seat, chute and yielding rubber pad, supporting seat bottom and axletree are fixed, chute inside is inserted on supporting seat top, after cooperation, with bolt connecting support seat and chute; Yielding rubber pad is arranged between supporting seat upper top and chute bottom; Axletree is connected by bearing with wheel.
The present invention adopts wheel and the integrated thinking of axle box, has cancelled independent axle box, and wheel is equivalent to the journal box body of traditional axle box, between wheel and axletree, adopts bearing to be connected, and has so just realized wheel and has independently rotated, and adopts inside suspension mode.Chute welded top, to underframe, plays and bears complete vehicle weight, transmitting tractive power, meets the functions such as locomotive turns to.Rubber shock-absorbing pad, for car load damping, ensures the stationarity of vehicle operating.
As the targeting scheme of preferred axletree and bearing, the shaft shoulder of bearing inner ring and axletree adopts interference fit, with bearing trim ring compression bearing inner ring and axletree.
As the targeting scheme of preferred wheel and bearing, wheel both sides are provided with inner end cap and outer end cap, and the seam of inner end cap and outer end cap and outside race compress.
The bearing that connects axletree and wheel adopts double-row conical bearing.Large bi-directional axial load can be born, the requirement of tractive force, braking force and the axial force of vehicle can be met.
Rear conveyance vehicle of the present invention portion out of shape, simple in structure, simplify manufacturing process, the production cycle shortens; Facilitate past-sale service; Every cover traveling portion manufacturing cost reduces by 1000～2000 yuan; Commonality is better, and the traveling portion of various rear conveyance vehicles (mortar vehicle, segment car) can be exchanged.
