Description
Technical field
The utility model relates to mechanical equipment technical fields, turn more particularly, to a kind of easy-to-dismount road sweeper steering wheel
To mechanism.
Background technique
The steering mechanism of existing Three-wheel type electric sweeper can be divided into two major classes, the first is the chainlet by axis of orientation
Wheel connection chain directly drives the big sprocket wheel of front-wheel rotating disk to change the direction of rotation of front-wheel rotating disk；Second is the side of passing through
It is directly engaged to the pinion gear of disk turning gear wheel shaft with arc-shaped rack and drives the work of front-wheel fixation kit.And second of steering mechanism
It is concerned because having the following advantages that: 1, being not susceptible to chain and get rusty or be broken；2, steering wheel rotational resistance is small, turns to and saves
Power.Have existed for second of steering mechanism, such as one kind disclosed in patent CN2011018773.3 in the prior art convenient for dimension
The road sweeper wheel steering mechanism of shield.The patent solves the disassembly problem of arc-shaped rack, but the patent is but there is under
State problem: since second bearing room and mounting base are by being welded together or being fixedly connected on one in underrun bolt
It rises, when gear fails, it is still desirable to remove entire front-wheel or mounting base just and can be carried out replacement, due to currently a popular
The self weight of sweeper be typically up to 700KG or more, therefore, it is extremely difficult to repair the steering mechanism.
Utility model content
In order to make up for the deficiencies of the prior art, the utility model provides a kind of easy-to-dismount road sweeper wheel steering
Mechanism.
The technical solution adopted in the utility model are as follows:
A kind of easy-to-dismount road sweeper wheel steering mechanism, including the upper mounting seat being connect with vehicle frame, the upper peace
First bearing seat is provided on dress seat, the main connecting shaft in the first bearing seat and front-wheel fixation kit is pivotally connected, the front-wheel
The lower end of fixation kit is equipped with wheel；It is additionally provided with second bearing seat in the upper mounting seat, is pivotally connected in the second bearing seat
There is steering wheel turning gear wheel shaft, the lower end of the steering wheel turning gear wheel shaft is transmission gear, is pacified on the front-wheel fixation kit
Equipped with the arc-shaped rack coaxial with the main connecting shaft, the interior tooth engagement of the transmission gear and arc-shaped rack simultaneously passes through arc-shaped gear
Item drives front-wheel fixation kit to rotate around main connecting shaft；The second bearing seat is fixed in upper mounting seat by limit plate, institute
The side for stating second bearing seat is equipped with groove, and the groove is adapted with the lug boss of limit plate, the protrusion of the limit plate
Portion is caught in groove, and the upper surface of the limit plate and upper mounting seat is detachably connected.The above-mentioned setting is so that the application is working as
It only needs to back out screw after the damage of components of second bearing seat, taking away limit plate can be realized the entire assembly of second bearing seat
Part takes out, and repair and replacement are extremely convenient.
Preferably, grease nipple is equipped in the first bearing seat and second bearing seat.Due to first bearing room and second
Bearing is mounted in bearing chamber, user can fill profit by increased grease nipple into first bearing room and second bearing room
Lubrication prescription greatly reduces bearing wear, extends sweeper service life.
Preferably, the limit plate is fixed by screws in upper mounting seat.
The utility model compared with prior art, it has the advantage that:
Convenient disassembly after the damage of components of the utility model second bearing seat, it is easy to repair, it is suitable for business promotion.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the structural schematic diagram in Fig. 1 at A.
In figure: 1, upper mounting seat, 2, first bearing seat, 3, front-wheel fixation kit, 4, wheel, 5, second bearing seat, 6, side
To disk turning gear wheel shaft, 7, transmission gear, 8, arc-shaped rack, 9, groove, 10, limit plate, 11, lug boss, 12, grease nipple.
Specific embodiment
As shown in Figure 1, 2, a kind of easy-to-dismount road sweeper wheel steering mechanism, including the upper installation being connect with vehicle frame
Seat 1 is provided with first bearing seat 2 in upper mounting seat 1, and the main connecting shaft in first bearing seat 2 and front-wheel fixation kit 3 is pivotally connected,
The lower end of front-wheel fixation kit 3 is equipped with wheel 4, due to installation and first bearing seat of the wheel 4 on front-wheel fixation kit 3
2 and the articulated manner of the main connecting shaft of front-wheel fixation kit 3 are the prior art, and therefore, details are not described herein.Upper peace in the application
It is additionally provided with second bearing seat 5 on dress seat 1, steering wheel turning gear wheel shaft 6, steering wheel rotate gear are articulated in second bearing seat 5
The lower end of axis 6 is transmission gear 7, is equipped with the arc-shaped rack 8 coaxial with main connecting shaft, transmission gear 7 on front-wheel fixation kit 3
Front-wheel fixation kit 3 is driven to rotate around main connecting shaft with the interior tooth engagement of arc-shaped rack 8 and by arc-shaped rack 8；Second bearing
Seat 5 is fixed in upper mounting seat 1 by limit plate, and the side of second bearing seat 5 is equipped with groove 9, groove 9 and limit plate 10
Lug boss 11 is adapted, and the lug boss 11 of limit plate 10 is caught in groove 9, and limit plate 10 and the upper surface of upper mounting seat 1 are removable
Connection is unloaded, limit plate 10 is fixed by screws in upper mounting seat 1.
